Freeblown Jar

Provenance: Jerry McCann Collection

Free-blown means glass-forming by blowing and manipulating by hand and tools without the aid of a mold to shape the bottle. A free-blown bottle has no mold seams or other mold-induced markings.

Our museum example represents a type of jar produced in the Pittsburgh District which typically comprises Louisville, Cincinnati, and Pittsburgh geographic areas. It was probably made somewhere between 1850 and the early 1860s.

This example was actually blown using a half mold form, probably wooden, to create the shape. The blown jar was turned in the half mold which often left horizontal scratches. The jar has an open pontil scar and an applied groove ring that allowed sealing with wax and a tin lid.

The vast majority of these jars are colorless, but deep blue and aqua examples are also known. Our museum example is quite exceptional in glass color.

The finish on these types of jars matched a variety of closures including glass stopper, glass top seal, Willoughby cast iron stopper, cork, and Kline. All have been reported by collectors.
